Urinary diversion for ureteral obstruction in the presence of recurrent colon carcinoma.

Selection of patients who might benefit from urinary diversion when recurrent colorectal cancer obstructs both ureters is difficult. Combinations of chemotherapy and radiation therapy will prolong a useful, comfortable and dignified life in some patients. Radiation therapy seems to be more effective than chemotherapy and, therefore, patients most likely to benefit are those with localized pelvic recurrences without carcinomatosis and those who are well nourished, active and highly motivated. Herein we discuss 6 patients who were diverted and the methods of selection.
